BRAKE -M ECHANISM FOR CARRIAG ES.

Application filed April 4,

T0 on whom it may concern:

Be it known that I, GUSTAV Frscnnn, a subject of the German Emperor, and a resident of Schoneberg, Germany, have invented certain new and useful Improvements inBrake Mechanism for Carriages and other Vehicles, of which the following is a specification.

My present invention relates to brake de-' vices for carriages and other vehicles, the object being to provide an improved device of this kind adapted to be readily operatedby a single action or movement executed from the drivers seat; and it consists in the features of construction and novel combination of parts fully described and claimed hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of an ordinary carriage with my improved brake device applied thereto. Fig. 2 is a bottom plan view of said carriage. Fig. 3 is an enlarged side elevation of the operating-lever and connections. Fig. 4 is a front view of same. tail view of the mechanism detached from the carriage.

On the platform of the carriage is suitably secured a bearing a, in which is journaled a revoluble pin p, one end of which carries the eccentric chain-wheel b. Said pin 13 has a portion which is square in cross-section to receive the correspondingly-apertured lower end of the operating-lever 0, adapted to be actuated by the foot of the driver. A suitable chain ol extends around and is secured to the eccentric wheel 1'), said chain passing over guide-pulleys e and f, suitably arranged on the frame of the carriage. Two brake-levers g g are fulcrumed on studs w w, secured to the under side of the carriage, the outer ends of said levers g g carrying the brake shoes h h, made of leather or other suitable material. One of said levers has at its inner end a circular opening 00', while the adjacent end of the other lever is provided with an elongated slot y. The inner ends of the levers g g are connected by a lever i by means of pins engaging said circular opening and said slot, respectively. Two coiled springs 70, attached to the carriage-frame and to the levers g g, as shown, haveatendency to hold Fig. 5 is an enlarged de- SPECIFICATION forming part of Letters Patent No. 656,450, dated August 21, 1900.

said levers normally in their inoperative position, in which the brake-shoes are not applied on the wheels of the carriage. Said springs serve also to raise the operating-lever 0 when the same has been depressed for applying the brake. The other end of the chain (1 is attached by means of an adjust able plate 1 to the lever 2', provided withabolt r and a thumb-nut 3, arranged in such a manher that said plate Z may be adjusted in ac cordance with the wear of the shoes h h. To this end the plate e is provided with holes i, one of which is engaged by the bolt r.

When it is desired to apply the brake, the driver. of the carriage depresses the operat ing-lever c with his foot, whereby a traction .is produced on the chain cl, so that both brakeshoes h h are applied on the wheels of the carriage. When the driver releases the lever 0, the springs 7c 7r operate to bring thev parts back to their normal position.

Having fullydescribed my invention, what I claim, and desire to secure by Letters Pat= cut, is-- i 1. In a brake mechanism for carriages and other vehicles,the combination with the frame and wheels of the carriage, of two brake-levers fulcrumed to the under side of the carriage frame and carrying suitable brakeshoes, a link-bar pivotally connected to the innerends of the brake-levers, an adjustable plate adjustably secured to said link-bar, a transmission-chain, or equivalent,attached to said adjustable plate and extending under the carriage to the drivers seat, a chain-wheel rotatably mounted near the drivers seat, said chain, or equivalent, extending around and secured to the chain-wheel, a suitable footlever adapted to rotate said chain-wheel and arranged within reach of the drivers foot, and means for normally holdingtlie various parts in their inoperative position, substantially as set forth.

2. In the improved brake mechanism as set forth, the combination with the fulcrumed brake-levers g, g, of a link-bar pivotally connected with the inner ends of said levers, a boltsecured on said lever, a perforated plate the perforations of which are adapted to be engaged by said bolt, a suitable nut screwed In testimony whereof I have hereunto set my hand in presence of two Witnesses.

GUSTAV FISCHER.

on said bolt to hold the perforated plate in position, a chain, or its equivalent, attached to the perforated plate, means for drawing said chain from the seat of the carriage, and 5 means for normally holding the various parts in theirinoperative position, substantially as lvitnessesz HENRY IIASPER,

set forth WoLDEMAR HAUPT.
